Compat for Filesystem clean up

README.md

@@ -143,6 +143,10 @@ Currently, the `@compat` macro supports the following syntaxes:
 
 * `remotecall`, `remotecall_fetch`, `remotecall_wait`, and `remote_do` have the function to be executed remotely as the first argument in Julia 0.5. Loading `Compat` defines the same methods in older versions of Julia. [#13338](https://github.com/JuliaLang/julia/pull/13338)
 
+* `Base.FS` is now `Base.Filesystem` [#12819](https://github.com/JuliaLang/julia/pull/12819).
+  Compat provides an unexported `Compat.Filesystem` method that is aliased to
+  `Base.FS` on Julia 0.3 and 0.4 and `Base.Filesystem` on Julia 0.5.
